I went on Sunday, to the Point Reyes National Seashore, and when I started I was thinking the route I had picked out was maybe, 16 or 17 miles, which is still further than I've hiked before. I quickly figured out that it would be longer than I had planned, but I had plenty of food, and, well, almost plenty of water, and I figured I'd just go ahead as planned anyway.
I started on the Five Brooks trailhead on Rte 1 and hiked the Stewart Trail up and over the ridge to the Wildcat Camp on the coast. That was the first 6.7 miles. I then proceeded south along the Ocean Lake Loop Trail (which features a great view point of the coast) to the Coast Trail, past Alamere Falls (at which point I took a .8 mile side trip to see the actual falls. There were naked guys there.) and Bass Lake to the junction with the Lake Ranch Trail, which was the previous northernmost point to which I had hiked the Coast Trail. Hiked back along the Coast Trail, then joined up with the Old Out Trail at 13.2 miles (including the side trip), took that back up to the Alamea Trail, which joined up with the Ridge Trail, merging with the Bolema Trail to the Olema Valley Trail and then back to the trailhead.
And then the aftermath. I was feeling very peppy for the first 13-14 miles or so, but the last six miles took their toll. When I got home at 7pm I called up my dad for Father's Day, showered, and then hopped straight into bed. I woke up with some strange aches and pains. I was sensible enough to stretch out all the obvious muscle groups during and after the hike, so my legs were ok. My butt was sore, which wasn't entirely surprising. But my ribs? My neck? And, of course, it turns out that a single application of sunblock is not near enough to get you through 9.5 sweaty hours. I guess I could have told you that beforehand if I'd thunk it through, but I'm a bit lobstery now.
I think the best thing I figured out was that taking a break, stretching, and then lying down with your feet elevated makes a big difference in staving off tiredness. Of course I'd read this before but never really tried it out. It was kind of nice.
